Bit Shift
Logic or arithmetic shift of the input signal.
Description
The Bit Shift block performs a logical or arithmetic shift of the input signal.
The behaviour of this block during simulation and code generation differs from the block Shift Arithmetic.
The Shift Arithmetic block shifts the bits or binary point of the input number. This block has additional options for code generation compared to the Bit Shift block. When a variable shift operation is required, use the Shift Arithmetic block instead of the Bit Shift block. If a signed number is input, the block performs a signed digit expansion.
Ports
Input
Port_1 - input signal
scalar | vector | matrix
Input signal for which a logical or arithmetic shift is performed.
